A proposal of good manufacturing practices (GMP) laboratory for CAR T-cell therapy in Latin America and the Caribbean: challenges and opportunities

Abstract

Chimeric antigen receptor (CAR) T-cell therapy is a transformative modality for refractory hematologic malignancies; however, its adoption in Latin America and the Caribbean (LAC) is severely constrained by prohibitive manufacturing costs, limited specialized infrastructure, and fragmented regulatory frameworks. To address this translational gap, we propose a pragmatic, cost-adapted model for establishing Good Manufacturing Practice (GMP) laboratories tailored to the socioeconomic realities of LAC. This model advocates for decentralized, modular cleanroom facilities that integrate fully closed automated manufacturing platforms with risk-based quality management systems. Furthermore, we emphasize the strategic implementation of artificial intelligence (AI) and digital health tools—such as electronic batch records and predictive analytics—to optimize resource utilization and ensure stringent regulatory compliance. Essential to this framework is the cultivation of a specialized local workforce and the promotion of regional regulatory harmonization through initiatives like PAHO’s Red PARF. Ultimately, this scalable approach provides a realistic roadmap to democratize CAR T-cell therapy in LAC, fostering regional biomanufacturing autonomy and promoting equitable patient access.
